1 Claim.

This invention relates to coin collecting apparatus for use at telephonepay stations, and more particularly to locking mechanism to prevent theunauthorized removal of such apparatus from its mounting.

It is an object of this invention to provide locking mechanism for usein connection with the mounting of telephone coin collecting apparatus,

elevation of a telephone coin collector showing the backplate thereofand its mounting plate in section, and with the improved locking mecha-Fig. 2 is a view, taken on a line 2-2 of Fig. 1. Fig. 3 is a sideelevation of the supporting plate upon which the coin collector ismounted, and Fig. 4 is a perspective View of the spring and pawlelements of the locking mechanism. Fig. 5 is a fragmentary view of therear surface of the backplate, showing openings in the form of key-slotsthrough which the mounting studs of the supporting plate arepreliminarily introduced. Fig. 6 is a cross-sectional view of Fig. 5showing a key-slot opening which extends from the rear surface'and partway through the backplate and connects with a substantially oval-shapedopening which extends to the front surface of the backplate, and Fig. '7is a fragmentary view of the front surface of the backplate showing theoval opening and a connecting key-slot opening appearing in the rearthereof.

, The locking mechanism of this invention is particularly adapted foruse with such mountings for coin collecting apparatus as is disclosed inO. N. Giertsen, U. S. application for patent, Serial No. 729,778, filedJune 9, 1934.

In the drawing, the main portion 5 of the coin collector housing isshown as being provided with a rear wall or backplate 6. V The collectoris adapted to be mounted by means of this backplate upon a supportingplate I which in turn is carried upon a vertical wall 8 of a room orbooth. In the mounting operation, the plate 1,- of course, is firstsecurely fastened to the supporting wall 8, and the backplate 6, onwhich the housing 5 is assembled, and which forms an integral unittherewith, is then secured to the plate. A cash compartment having adoor is provided in the housing 5 through which access may be had tolocking mechanism for securing the housing to the supporting wall aswill be presently described.

As shown in Fig. 3, the supporting plate i is provided with a series ofextensions or buttonhead studs 9 having their shanks integral with orsuitably affixed to said supporting plate. The plate l is rectangular inshape, similarly to the haclrplate 6, and the studs 9 extend forwardlyfrom its front surface, and may be suitably spaced from each other andof any number desired. The backplate 6 is provided with a correspondingnumber of spaced holes it) which are preferably of inverted key-slottype, as more clearly shown in Fig. 2, and are adapted to register withsaid studs. The lower, openings of said slots are larger than the upperopenings. The key-slots is extend from the rear surface and part waythrough the backplate 6 and-are of a depth slightly less than the lengthof the shank portions of the studs 9. These slots connect with depressedor counter-sunk openings E8 of somewhat oval shape (Figs. 6 and '7)which extend forwardly from the key-slots It to the front surface of thebackplate 3, and said counter-sunk openings are of a depth substantiallythat of a thickness of the button-head portions of the studs 3. Thelower portions of the counter-sunk holes lie in coincident relation withthe lower or larger openings in the key-slots I0, and permit the initialentrance of the button-head portions of the studs 9 through thebackplate when the collector is mounted on the supporting plate I. Theupp penings of said counter-sunk holes, extend above the top edge ofthe-restricted or upper openings' of the key-s1ots and provide a seatfor said button-head portions of the studs 9, while their shank portionsregister in the restricted openings in the key-slots I0.

In the mounting operation of the coin collector housing backplate on thesupporting plate I, the button-head portions of the studs are firstintroduced through the lower portions in the keyslots and counter-sunkopenings. As the collector is lowered to its seated or mounted positionthe button-head portions of the studs pass intothe upper portions of thecounter-sunk holes and the shanks of the studs pass into the restrictedopenings of the slots, and the buttonhead portions of said studsregister in the upper portion of the counter-sunk opening. In thisposition, the backs of the button-head portions of the studs are heldsnugly against the front surfaces of the upper portions of thecountersunk openings l8, and thus secure said backplate and suppqrtingplate in rigid interengaged relation, When the button-head portions ofthe studs are in position their outermost surfaces lie flush with thefrontsurface of the backplate 6. The lower portions of the counter-sunkopenings iii are vacant under this condition, and locking mechanism isassociated therewith to fortify against the unauthorized removal of thecollector from its mounting, as will be presently described. Additionalmeans such as flat-headed screws may be provided, if desired, to holdthe backplate and supporting plate together.

A latching device, as more clearly shown in Fig. 4, is provided for atleast one of the countersunk openings associated with the key-slots.This latching device, in the present instance, is positioned upon thelower portion of the backplate 6, and preferably back of a return chute(not shown) which is ordinarily located at the left side of the coincollector. The latching device includes a spring member !2 which liesfiatly against the face of the backplate 6, and is shown as havingopenings through which screws l3 pass and engage said back member. A lugor pawl M is carried by the spring 92 and may be integral or attachedthereto by means of a nut and bolt 55, as shown in Fig. 1; The springnormally holds the pawlseated within the vacant lower part of therecessed hole. The lower end of the spring member may be provided withan aperture through which a screw 56 passes loosely into the backplate6. The head of this screw provides a stop to prevent excessive backmovement of the pawl M which might result in the distortion of thespring member l2.

In the mounting operation of the coin collector upon the supportingplate 1, as previously described, the insertion of the button-head studthrough the lower opening in the key-slot ID will result in the pawl I 6being pushed out of this opening and out of the lower portion of therecess l8. When the collector is lowered to its seated or mountedposition, the shank of the stud registers in the upper or restrictedopening of the key-slot l0, and the button-head portion of the stud liesin the upper part of recess l8 with its lowermost part extending evenwith or very slightly below the intersection of the lower larger openingand the upper restricted opening of the key-slot H3. The pawl M is ofsufiicient size to occupy the vacant space provided in the lower portionof the counter-sunk opening, and when in position, it abuts thelowermost part of the button-head portion of the stud 9. The pawlautomatically enters this opening when the stud is in the positiondescribed, and is resiliently held therein by means of the spring 12.The backplate and supporting plate are thus automatically locked ininterengaged relation to maintain the coin collector in mountedposition. It will be apparent from the foregoing that said collectorwill be fortified against unauthorized removal when in the lockedposition described.

If desired, the coin collector may be removed from its mounting byauthorized persons by unlocking-and removing or opening the cashcompartment door (not shown) of the collector. When the compartment doorhas been removed or opened access may be had to the interior of the coincollector, and the pawl l4 may be disengaged from its position-in thespace under the buttonhead of the stud. The collector may be then liftedand released from engagement with the studs 9.

What is claimed is:

A mounting for telephone coin collectors including a supporting slotstherethrough, a backplate having buttonhead extensions thereon adaptedto pass through and into the smaller and upper portions of said slots tohold the supporting plate and backplate in interengaged relation, andlatching means for automatically locking the supporting plate andbackplate in their interengaged positions said latching means includinga spring plate carried by the backplate and having a projection platehaving inverted keytherefrom adapted to be engaged in the larger 40 andlower portion of at least one of the key-slots to prevent thedislodgment of the button-head extension from the upper slot andautomatically lock the supporting plate and backplate in interengagedrelation.
